y Application` `filed` April 17, 1922. Serial No., 553,820.

The presentinvention relates to looseleaf` i binders orthe like, yand aime to provide certain improvements therein.

An .object-.of the presenthiiivention 1s to which will be adapted to" holdloose leaves `isecurelyin place and which may be adjusted toaccommodate a greater or less number ofi leaves. `It is also'an 'object of the present invention that the` device 'be simple in con*l struction, effective in opera-tiem, and one ohthat may befnianufactured and sold at a low price.

To this end the invention comprises a loose leaf device having a binder consisting of a pair of adjustable telescopic members, one of which is tubular and provided with lateralopenings in its side, and the `other of which is formed with a pair 'of spring ,lingers Iformed at their free ends with a 'lateral projection adaptedvto enter anopen ing in the tubular member. The invention also `contemplates the combination of such binder post with a substantially semi-circular element which may serve to hold the n leaves and which is preferablyA formed to have a quick detachable connection with 1said binder post. Certain other features of improvement are 'also contemplated, and

will be hereinafter more fully set forth.

Referring to -the drawings, wherein I Ahave 'shown 'the preferred embodiments of my invention,-

S is a side elevation of the extension member shown in Figa 7. V

Referring first to Figs. l to 6 of the drawings, let A and A yindicate the covers and B the back of a loose leaf binder. The back and `covers are preferably lieXibly connected together; as Ishown at'C. A

For the purpose of holdingthe leaves between. the binder covers, l employ a substantially semicircular or U-shaped `elevment D. lt is preferable that this element be resilient and provided with an initial outward tension tending to move its ends apart for a purpose to be hereinafter set forth. This element is preferably carried y a binder post formed of a pair of telescopic sections .E and F, and acts against said binder post adjacent its ends to urge the telescopic members thereof apart.

lhile any suitable connection betweenthe binder `post members and the elementl D may be resorted to, l prefer to employ the connection herein disclosed, `which consists in one end of the. element l) being looped varound the post F, `as shown atri,y andthe other end being formed with notches d adapted to engage and hold against the lower-most edge of one ofthe grooves e. rihe element D being resilient and provided 'with an initial ontwardtension, it will. be appreciated that by the means just `described a quickly attachable and` detachable connection between the binder post and the element D is provided. To accommodate liiferent thicknesses of leaves between the covers, members lil and F are made longitudinally adjustable. This is accomplished by forming the member E, which is tuality of openings e in its sido, and forming the member F with a pair of spring arms j, f', the free ends of said arms `being each provided with a lateral catch projection f2 adapted toengage inthe openings e of the tubular memberv E, owing to thc initial outward tension pos sessed by the spring Lngers f. The members E and F may be carried bythe back member B iny any suitable manner, but l have found that by permanently seably beveled, as indicated at f3, and to pro-y vide for the facile disengagement ofk said catch projections from thev opening e, the sides of said projections are beveled.y as indicated at f4, as best shown in Fig. 6. It

will thus be seen that When the projections lare in locking engagement with the open-l ings in the tubular member, that by turning the member F through an angle of 90, a

. complete disengagement is accomplished.

Such turning movement may be accomplished by rotating the head f5 either with the lingers or by applying any suitable instrument to the kerf f6 in the head f5.

In Fig. 7 I have shown the employment of an additional extension member I cooperating With the telescopic members rl and F. By the employment of such extension member, the binder device may be made to accommodate an amount of leaves of greater thickness than the maximum degree of extension when only the elements E and F are employed. This extension member I in construction embodies the feae tures of both the telescopic members E and F, and is adapted to simultaneously telescope With both of said members. In construction it consists of a tubular part J having openings y' in its side, and a pair ofk spring lingers K each formed at its free' end with a lateral projection 7c. The parts J and K are substantially the same in construct-ion as the parts E and F respectively, and in use theY part J is adapted to receive the binder post member F, While the part K is adapted to enter and be received by the hinder member E. D may be used in combination With this binder post. in the samey Way as With that disclosed in Fig. 1.

In the use of the device, the leaves are carried by the element Dl and the binder post members E and F telescoped together to the proper degree, depending on the amount of leaves held by said element. In varying the effective length of the telescoping members E and F, the effective length of the 'element D, that is the length of the chord joining the ends of said element is also varied, but the effective length of the element D which is necessarily different for every adjustmentL of the members E and F does not vary when the covers of the device are opened or closed. When it is desired to add or remo-ve any leaves, the coverl is opened and the end adjacent the notches al made free by applying there- A resilient member to a slight upward pressure. After the addition or removal of leaves, the telescoping members E and F are respectively Withdrawn or contracted, as found necessary, and the notch cl again caused to engage in the Wall of the opening c.

l/'Vhile in the embodiments of the invention herein disclosed the element D is primarily designed to hold the leaves, it Will be appreciated that, if desired, this element may be dispensed with and the leaves directly held by the binder post elements. In this event,vvhen it is desired to add or remove leaves, the binder post member F must be entirely Withdrawn from the tubular member E. However, if the leaves are formed With slotted openings a complete separation of thebinder post elements is not necessary, but a mere extension of said members would suftice to permit the addition or removalv of such leaves. Hence, it Will be appreciated that the present invention contemplates the use of the binder post Velements vwith or Withoutthe semicircular leaf-holding element. I.

lVhile- I have shown and described the preferred embodiments of my invention, it will be understood that I do not Wish to be limited to the specific construction herein set forth, since various changes therein may.v

be resorted to Without departing from the spirit of the invention.

`What I claim is 1. A loose leaf binder comprising a pair of telescopic members having interengaging means and a resilient element connected With said members adjacent their remote ends.

2.. A loose leaf binder comprising a pair of telescopic members having interengaging means, and a resilient element adapted to hold the leaves connected- With said mem'- -bers adjacent their remote endsand acting to urge them apart.

3. A loose leaf binder comprising a binder post and a substantially semi-circular element for holding the leaves, one end of the semifcircular element having a quickly detachable connection with the binder post.

4:. A loose leaf binder comprising a pair of adjustable telescopic members, one being tubular and formed with a longitudinal series vof openings in its side, and the other having a pair of spring fingers formed at their free ends with a catch projection adapted to enter an opening in the first member to lock the member against separation, the catch projections being beveled on their under side to freely ride through the tubular member, and beveled at their sides so that by slightly rotating the spring iinger carrying member the catch projection Will be released from the opening.

5. A loose leaf binder comprising a pair of members adapted for' telescopic connection with each other and an extension memed to receive therein one of Jshe pair of her adapted to simultaneously telescope with members, and the spring fingers adapted to the pair of members, said extension mementer the other of the pair of members. l0 ber having a tubular portion provided with In Witness Wheleo'f, I have hereunto openings in its side and a pair of spring {in- Slgned my name.
